Abstract: 625,011. Making hollow-ware. LEER, W. VAN. Oct. 27, 1945, Nos. 28446/45 and 17214/46. [Classes 83 (ii) and 83 (iv)] Cupping; embossing.-In a method of manufacturing hollow metal articles, a circular disc is drawn by a punch through a series of ring-like dies, the first of which causes the blank to form a cup on the end of the punch without any substantial reduction of thickness of the metal and the others of which are reducing dies cooperating with the punch to reduce the wall thickness of the cupped blank. The disc 12<SP>1</SP> of aluminium or other suitable metal is held between the first cupping die 17 and a holding ring 10 which is operated to engage the work by cams acting through resilient means. The punch 7 is water-cooled and is moved by a crank so that it engages the disc and moves it successively through the cupping die 17 and three reducing dies 19, 21 and 23. Lubricating pads 24, 25 and 26 are arranged between the dies. At the forward end of its stroke, the punch moves the work clear of the die 23 to a position where it is surrounded and gripped by cam-operated semi-cylindrical stripping members 15, portions 35 of which embrace the punch behind the work so that stripping occurs as the punch begins its backward movement. The end of the punch may co-operate with an embossing die 37 to emboss the bottom of the container or other article. The cupping die 17 has a cylindrical opening and each of the drawing dies a tapering portion 27 leading to a cylindrical portion 28, the two portions making an angle of ten degrees.
